dsp presets and better pan adapter

Better noise reduction workflow for DX

AetherSDR already has a strong DSP foundation, but for practical HF/DX operating it would be very helpful to have:

DX-focused DSP presets for common conditions such as:
static / QRN
pulse noise
weak-signal DX
crowded band / heterodyne conditions
Quick A/B comparison between NR/NB/ANF/TNF options
Per-band and per-mode DSP memory, so settings can be saved and recalled automatically for bands like 80 m, 40 m, 20 m, etc.
A more refined weak-signal optimisation mode that helps pull out marginal DX without making the audio sound too processed

For DXing, the display is just as important as the audio. It would be great to have:

a sharper high-definition panadapter mode
improved weak-signal peak definition
peak hold / max hold
better signal snap-to-peak / centroid accuracy
improved noise-floor scaling so weak stations stand out more clearly
an optional quality vs CPU performance setting so users can choose smoother or sharper rendering depending on their hardware

No files, tests, or entry points are named. Start by locating the DSP controls for NR, NB, ANF, and TNF and the panadapter rendering path, then determine how presets, per-band and per-mode memory, peak handling, and quality-versus-CPU settings would fit together. Done requires a defined, scoped implementation plan rather than the full wishlist.
